' EXPLOSIVE-MOTQR.

SPECIFICATION forming partY of Letters Patent No. 618,638, dated. January 31, 1899.

Application filed January 8, 1898.

To @ZZ whom it may concern: l

Be it known that I, EUGNE BRILLI, a citi- Zen of the French Republic, residing at Paris, France, have invented certain new and useful Improvements in Explosive-Motors, (for which I have received a patent in France, No. 267,818, dated .lune 12, 1897;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in explosive-engines of the four-phase system wherein two cylinders cooperate in such a Way that a motive impulse is obtained at each revolution.

The improvements embody, first, the disposition of the means serving to prevent the perturbations resultant from the inertia of the masses in motion, and, second, the use of a pump which at each revolution displaces or shift-s alternately the gases in the neutral spaces in one and the other cylinder after each exhaust and which. determines at a given moment the injection of air intended to effect the pulverization of the liquid fuel (coal-oil, gasolene, dac.) in case the engine is fed bysuch.

In the accompanying drawings, Figure 1 is a section through the aspirating-valves which are operated by an auxiliary shaft. Fig. 2 is a section through the middle ofthe airpump. Fig. 3 is a section through the middle of one of the cylinders; and Fig. 4 is a section through the middle of both cylinders, showing the motor-shaft in side`elevation.

In said figures the cylinders are designated by the numerals 1 and 2.

3 5 and 4 6 are the pistons, which travel in pairs in opposite directions to each other. Two of these pistons, 5 and 6, are connected to the main shaft 12 13 14 15 16 by means of pitmen 7 S, Which` act upon the crank 14, and the two others, 3 and 4, are connected by pitmen 9 and 10 to cranks 13 land 15, opposite the crank 14, or at an angle of one hundred and eighty degrees thereto, said pitmen 9 and 10 being united by a transverse bar 11.

conduit 27,- which communicates through a port 26 with the air-pump 23.

All of the valves "are operated by cams keyed on the two shafts 21 and 22,'which rea volve at half the speed of the main shaft. The compression cylinder or pump 23, Fig. 2, is inclined at an angle of forty-iive degrees, more or less, to the cylinders 1 and 2. Its piston 24 is moved by a pitman 25, which is connected to the middle part of the crank 14 of the main shaft. (Omitted in Figs. 3 and 4 for the sake of clearness.)

The compression-cylinder is connected, first, through port 26 with conduit 27, as already stated, said port being adapted to close at a predetermined period when the piston 24 is moved; second, by means of the opening 33 with the conduit 31 32 in the piston 24; said port registering at a given moment with said conduit and being connected by a suitable pipe to a coal-oil pulverizer, as indicated in Fig. 2 by dotted lines, and, third, `with an aspirating-valve 34.

Having described its principal parts, I shall now explain the operation of the engine. When the main shaft rotates, the pistons 3 and 4 move in an opposite direction to the pistons 5 and 6 whether receding from or approaching the same. The throw of the crank 14 is made greater than thatof the cranks 13 and 15, so that the pistons 5 'and 6 travel with a greater speed than the pistons 3 and 4. It results therefrom that the inertia of the mass of said pistons 5 and 6 and their pitmen 7 and 8 being smaller than the mass of the pistons 3- and 4 pitmen 9 and 10 and transverse bar 11 will easily compensate the inertia of the latter, and thus the engine is equilibrated. The explosions alternate in each cylinder in such a manner that a motive impulse is effected at each revolution.

The working phases are the following:

At each revolution of the main shaft in the direction of the arrow, Fig. 2, the piston 24 will drive a certain quantity of air into the chamber 30. Simultaneously the valve 20 closes and cuts off communication with the outer atmosphere. At this moment exhaust commences in one or the other cylinder. Under the action of a cam on shaft 21 one of the valves 18 or 19 (the one corresponding with the cylinder under exhaust) will be lifted and will allow the air furnished by the pump to pass through, which drives before it through the exhaust-valve the gases accumulated between the pistons. At the end of the stroke of the pistons, when they are convergent or nearing each other-that is to say, at the end of the exhaust-the piston 24 in continuing its stroke closes the conduit 2G, and the air is then compressed in the pump. rlhis air at a predetermined moment escapes through conduit 32, when the latter registers with opening 33, so that the air is in part discharged into a pulverizer 37, from which the liquid is forced through conduit 29 into the chamber 30 at the moment when one of the cylinders l or 2 commences its aspirating period. At this moment the valve 2O opens and the outer atmospheric air entering through opening 28 is passed into the cylinder mixed with carbureted air. The aspiration of the pump 23 at first draws in air through valve 34 and then aspirates the same through the conduits 26 and 27.

The port 33 may be dispensed with when a liquid fuel is not used-for instance, when gas is employed as the explosive element. In this instance the conduits 31 32 and valve 34 Would also be superliuous. In this case the piston 24, having closed the port 26, compresses air in the pump-cylinder, which serves at the back stroke to restore the power consumed by said compression.

Having now described my invention, I claim- 1.
